FIELD OF THE INVENTION

The present invention lies in the field of telecommunications. The present disclosure relates to alignment of communication antennas.

BACKGROUND OF THE INVENTION

An essential part of a wireless service provider's business is its ability to provide adequate communication capabilities to its customers. In order to provide said capabilities, wireless service providers deploy communication antennas on towers, rooftops, buildings, and other tall structures. The height of such structures allows the radio signal from each communication antenna to travel several miles, establishing a geographic area within which service may be provided to customers. Wireless service providers typically install several directional communication antennas per site as multiple directional communication antennas are needed for increased capacity and reception.

In order to provide the required radio signal throughout a defined area, each directional antenna is intended to face a specific direction (referred to as “azimuth”) relative to true north, to be inclined at a specific downward angle with respect to the horizontal in the plane of the azimuth (referred to as “downtilt”) and to be vertically aligned with respect to the horizontal (referred to as “skew”). Undesired changes in azimuth, downtilt, and skew will detrimentally affect the coverage of a directional antenna. These alignments may be likened to the axes commonly used to describe the attitude of an aircraft: Azimuth corresponds to the yaw of an aircraft about a vertical axis; skew corresponds to the roll of an aircraft about its longitudinal axis; and downtilt corresponds to the pitch of the nose of an aircraft above or below a horizontal plane (or about a lateral axis extending horizontally through the aircraft at right angles to the longitudinal axis). In general, the more accurate the installation, the better the network performance that may be achieved within the area served by the antenna. Directional antenna installations are performed by tower companies who use certified tower climbers to carry out these installations.

Due to inaccurate and user subjective antenna installation techniques used by many tower companies, a need has grown for the use of GPS Antenna Alignment Devices. These devices for many years have been very large in size and challenging to attach to the host Antenna.

Thus, a need exists to overcome the problems with the prior art systems, designs, and processes as discussed above.

Herein various embodiments of the present invention are described. In many of the different embodiments, features are similar. Therefore, to avoid redundancy, repetitive description of these similar features may not be made in some circumstances. It shall be understood, however, that description of a first-appearing feature applies to the later described similar feature and each respective description, therefore, is to be incorporated therein without such repetition.

Described now are exemplary embodiments of the present invention. Referring now to the figures of the drawings in detail and first, particularly to FIG. 1, there is shown a first exemplary embodiment of an antenna alignment device. The radio-frequency (RF) aligner, e.g., device 100, uses a global positioning system (GPS) receiver in order perform an antenna alignment. Device 100 houses components that include a battery 115, a GPS Receiver 110, GPS Antennas 125, a touch sensitive flat panel display 120, an on/off switch 130, and an interconnect circuit board 105.

Interconnect circuit board 105 includes one or more processors 135 (e.g., central processing unit (CPU) and one or more memory elements 140 (e.g., random access memory (RAM) and/or read only memory (ROM).

It should be understood that software modules running in the interconnect/aggregator circuit board 105 can be implemented as one or more physical devices that are coupled to the CPU 135 through a communication channel. Software running on device 100 can be represented by one or more software applications (or even a combination of software and hardware, e.g., using application specific integrated circuits (ASIC)), where the software is loaded from a storage medium, (e.g., a magnetic or optical drive or diskette, or a solid state drive (SSD)) and operated by the CPU 135 in the memory 140 of the interconnect circuit board 105. Examples of a solid state drive can be flash memory, a SSD hard drive, and a secure digital (SD) memory card. As such, software modules (including associated data structures) of the present invention can be stored on a computer readable medium, e.g., RAM memory, SSD, magnetic or optical drive or diskette and the like.

Device 100 houses all the components mentioned above within a small and light-weight enclosure 200 as shown in FIG. 2, FIG. 3, FIG. 4, and FIG. 5. Device 100 can also house the components mentioned above within a small light-weight enclosure 300 as shown in FIG. 6, FIG. 7, FIG. 8, FIG. 9, FIG. 10, FIG. 11, FIG. 12, and FIG. 13. Features of enclosure 200 also apply to enclosure 300 and vice versa. In one particular embodiment shown in FIG. 12, the device has a length of 18.75 inches, a width of 5.375 inches. In this embodiment, the rear portion of the enclosure 300 has a height of 4.125 inches and the weight of device 100, 300 is approximately 3.675 pounds.

Device 100 has a built-in touch sensitive flat panel display 1, 120 that is used as a graphical user interface. Device 100 also has a very sensitive GPS compass that is accurate to within ¾ of a degree.

The touch sensitive flat panel display 1, 120 is a built-in touch screen. Prior art alignment device makers do not tend to use touch screens because they create a significant amount of noise for the GPS. The touch sensitive flat panel display 1, 120 is placed or secured within a chamber of the enclosure 200, 300. The touch screen chamber is shielded to reduce the amount of noise affecting the GPS system/readings. In one embodiment, the touch screen chamber is painted with copper paint to shield the emissions radiated from the display 1, 120 and thereby reduce interference with the GPS. In one embodiment, wiring internal to the enclosure for On/Off switch 8, 130 is also shielded.

The enclosure 200, 300 includes a top portion 45 and a bottom portion 50. In one embodiment, the top portion 45 is substantially flat. The top portion 45 and bottom portion 50 of enclosure 200, 300 are attached to form a single mold, e.g., enclosure 200, 300, that includes all components needed for the alignment device 100, 200, 300.

The enclosure 200, 300 of the present alignment device has a single radome, e.g., antenna cover, for a plurality of antennas. The top portion, e.g., the cover of enclosure 200, 300, is substantially flat and is one piece. Thus, the top portion of the enclosure 200, 300 can be considered a single radome. Having a single radome, among other advantages, reduces assembly costs, uses less parts, and provides less points of failure. Prior art alignment devices tend to either have multiple housings or multiple radomes for their antennas. For the purposes of this disclosure, a radome is defined as a protective cover for one or more GPS antennas that is transparent to radio waves.

The enclosure 200, 300 has a mounting knob 2, which may, in one embodiment, comprise a single Pem-nut, for mounting to an antenna clamp or directly to an antenna. The mounting knob 2 can also be used to mount the device on a standard tri-pod or monopod. When the enclosure 200, 300 is used on a standard tri-pod or monopod, the alignment device can be used on the ground to provide a rough verification for the device operator.

In one embodiment, enclosure 200, 300 has an attachment mechanism to keep the enclosure from falling. The attachment mechanism has one or more openings, e.g., carabiner attachment 11, for attaching a lanyard or rope that is used to tie off or tie-down the device in case of an accidental drop. In one embodiment, enclosure 200, 300 has built-in sighting notches 6 that provide accurate positioning. In one embodiment, the enclosure 200, 300 has a built-in handle for the purpose of carrying the device.

Enclosure 200, 300 has a built-in universal serial bus (USB) communication port 4 that can be used to retrieve saved measurement reports and update firmware. Enclosure 200, 300 also has a built-in battery charging port 5 that is used to charge the battery. In one embodiment, the battery may be a lithium ion battery. The USB communication port and battery charging port are coupled to circuit board 105. Enclosure 200, 300 has a built-in on and off push button. In one embodiment, the enclosure 200, 300 has a rubber cover 3 that is used to protect the USB and charging ports from dust and moisture.

Enclosure 200, 300 has sighting guides 6 that are used, for example, with a monopod to remotely verify antenna azimuth. GPS antennas (not shown) are within enclosure 200 and placed near the areas denoted by element 7. GPS antennas are used so that the device can display azimuth, latitude, longitude, height, date, and time. On/Off Switch 8, 130 is used power the device on and off. Carrying handle 9 is used to carry the device 100, 200, 300. The monopod attachment hole 10 is used to attach a monopod to the device.

FIG. 14 is a universal antenna clamp 600. Clamp 600 attaches to a directional panel antenna shown in FIG. 15 and FIG. 16 as antenna 705. Clamp 600 also supports the enclosure 200, 300 as shown in FIG. 16.

Clamp 600 to attaches to the back of a directional panel antenna. Clamp 600 clamps the sides of an antenna in order to secure the clamp to an antenna. Clamp 600 supports multiple directional panel antenna widths. Clamp 600 has supporting arms that act as a support for the enclosure 200, 300. Clamp 600 has a mounting hole used to affix the enclosure 200, 300 to the universal antenna clamp 600. Clamp 600 has one opening used to attach a lanyard or rope that ties off the device in case of an accidental drop.

Clamp 600 includes an adjustment pin 21. The adjustment pin 21 is raised in order to adjust the width of the clamp 600. Pin holes 22 are used with the adjustment pin. Back bar 23 is aligned with a back bar of the antenna 705. Unit mounting holes 24 are used to mount the device 100, 200, 300 with mounting knobs. Clamp mounting arms 25 are used to support the device 100, 200, 300. A rubber compression pad 26 is used to affix the clamp 600 to the antenna 705. A tightening knob 27 is used to tighten the clamp 600 onto the antenna 705. A carabiner attachment hole 28 is used to carry or tie-off the antenna clamp.

The built-in touch sensitive flat panel display 120 displays measurements derived by the GPS receiver and has the ability to take screen shots for later viewing. In one embodiment, the screen shot picture files are encrypted in order to ensure validity. In one embodiment, a code is used to encrypt a “.bmp” file in order to authenticate the screen shot. In addition to the screen shot, a text file with the raw data can also be provided. A user of the device 100, 200, 300 can view files on the display 120, for example so that the user can check what was done, e.g., verify that the job was done correctly, before climbing down. In addition, validation software can be used when files from the device 100, 200, 300 are uploaded from the device. The validation software can be used to verify that the results are actually from the device with the encryption code used for authentication.

A file menu of the device is presented on the display and is used to recall or review previously saved screen shots or reports to verify that the input data is correct. The input data can be, but is not limited to, antenna identifying information. The antenna identifying information can be an antenna site/location, an antenna sector, and/or an antenna position.

In prior art devices, the data is saved and post-processed later. Thus, users of prior art devices would not be aware of any mistakes that were made until after they left the site.

In one embodiment, device 100 has an improved GPS Performance/Boost mode, which reduces system noise in order to increase GPS performance. Every component, e.g., battery, display, etc., of the device 100, 200, 300 emits a certain level of radiation. This emitted radiation causes a long delay in determining the azimuth. The present device 100, 200, 300 provides a GPS boost mode that reduces noise in the entire system 100 to make a GPS signal stronger. This mode allows the determination of the azimuth (bearing) in approximately 30 seconds instead of 2 to 5 minutes. In one embodiment, the device 100, 200, 300 reduces processor speed, no longer accesses random access memory (RAM), and lowers current consumption to reduce the noise of the entire system and improve GPS reception.

In one embodiment, the device 100, 200, 300 can be used on the ground as a surveying tool using sighting guides 6 of FIG. 3.

In one embodiment, device 100, 200, 300 can be used to provide information that can be used in windmill technology. Device 100, 200, 300 provides a correct reference for a first wind reading. Device 100, 200, 300 is used as a compass so that the windmill can be moved in the direction of the wind.

In operation, device 100, 200, 300 interprets data received from the GPS. The device 100, 200, 300 can be used to align antennas and microwave dishes.

When the device 100, 200, 300 is used to align microwave dish antennas, example calculations provided by the device may include azimuth, tilt, and distance. An accelerometer of GPS 110 is used to measure tilt. Given the latitude/longitude/height of the receiving dish, device 100, 200, 300 calculates the azimuth and tilt, and also shows the distance, i.e., between the device (where are first dish is to be placed/aligned) and a second dish in a different location.

For a given position (e.g., latitude/longitude) and height above sea level, the device 100, 200, 300 can calculate the direction between two points. For example, when the device 100, 200, 300 is at a first point, the latitude/longitude and height are read and known by the device. The latitude/longitude and height for a second point can be provided as input to the device. From the information known for the first point and input for the second point, the device 100, 200, 300 can calculate azimuth and tilt. In one embodiment, azimuth, tilt, and distance, can be shown to the user on the display 1, 120.

Using prior art devices, it is difficult to align microwave dishes because the operator cannot see the second point. Possible obstructions to seeing the second point include fog, buildings, etc. Prior art methods for aligning microwave dishes used balloons, lasers, flags, two teams using signal strength meters, and other methods to assist in aligning the microwave dish. Using the alignment device of the present disclosure, the second point does not have to be visible in order to properly align the microwave dishes.
